Check Digit Verification of cas no

The CAS Registry Mumber 49641-17-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,9,6,4 and 1 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 49641-17:
(7*4)+(6*9)+(5*6)+(4*4)+(3*1)+(2*1)+(1*7)=140
140 % 10 = 0
So 49641-17-0 is a valid CAS Registry Number.

Selenium-catalyzed reductive cyclization and carbocyclization of 2,2′-dinitrostilbenes with carbon monoxide: One-shot synthesis of indolo[1,2-c]quinazolinones

Umeda, Rui,Morishita, Shigeru,Nishiyama, Yutaka

, p. 571 - 575 (2012/02/15)

When 2,2′-dinitrostilbene derivatives were allowed to react with carbon monoxide in the presence of a catalytic amount of selenium, reductive cyclization and carbocyclization proceeded to give indolo[1,2-c]quinazolin-6(5H) -ones, containing both indole an
